QR Code

Recently I noticed there are these weird looking square images used in banners, advertisements in the internet and as well as on the road. So I did some research on it and was able to find out what it is. Its called a QR Code.



QR code stands for quick response code. This was used by the Toyota company to track vehicles in the manufacturing process in 1994.

I believe it seems to be a quick way to send messages using a security facility.
The internet has websites in encoding and decoding the QR Code.
